COW-TAIL HOLDER.

To all whom it may concern Be it known that I, OSKAR NELssoN, a citizenof Sweden, residing at Hampshire, in the county of Kane and State ofIllinois, have invented certain new and useful Improvements in Cow-TailHolders, of which the following is a specification.

This invention relates to devices for holding cows tails during themilking operation or at other desired times.

The object of the invention is to provide an improved device of theclass that is simple in construction and operation and positive inaction. A further object is to provide a device of the kind that ishumane and not painful to the animal when in operation.

A further object is to provide a device of the class having separatejaws for engagement with the leg and tail of the cow so that theinstrument may be permitted to remain upon the leg when not in use tohold the tail thus obviating possible loss of or misplacement of thedevice.

Another object is the provision of a positive lock rendering withdrawalof the tail by the animal an impossibility.

With the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be herein after fullydescribed in the following specification, pointed out in the claim andillustrated in the accompanying drawing which forms a part of thespecification and in which Figure 1 is a fragmentary side elevationshowing my device in use. Fig. 2 is a plan of the device partly insection. Fig. 3 is a vertical section taken on line 83 of Fig. 2.

Like reference characters indicate corresponding parts throughout theseveral views.

The device comprises a pair of jaws 1 and 2 terminating in handles 3 and4 respectively. Between the said jaws a tongue 5, converging to a pointat its lower end, is supported upon a pin 6, the ends of the said pinbeing embedded in the aforesaid jaws and the body of the pin beingpierced by a tiny transverse pin 7 the ends of which are embedded in thetongue 5; the purpose of this arrangement being ,to avoid movement ofthe tongue in a plane parallel to the vertical planes of the jaws.

8 is a spring having either end fastened in a transverse recess ineither jaw and ex- Specification of Letters Patent.

tending through a transverse aperture 9 in the tongue 5, the purpose ofthe spring being to draw either jaw firmly against the said tongue.

Near the forward end of the jaw 1 the same is provided with asemi-circular recess 10 which is disposed directly opposite a similarrecess 11 in the tongue 5 and the jaw 1 is partly cut away as at 12 uponits surface adjacent the tongue from the circumference of the recess 10to a point below the spring 8 so that the ends of the said jaw and thetongue '5 may be held firmly against each other. A transverse aperture13 is provided in the jaw 1 between the recess 10 and the forward endand through this aperture a bolt 14, secured to the tongue 5, extendsand the free end thereof projecting beyond the said jaw is securedagainst withdrawal by a transversely extending pin 15.

Referring now to the jaw 2 the same is provided upon its inner side nearthe forward end with an enlarged somewhat semicircular recess 16 and asimilar recess 17 located directly opposite is formed in the adjacentface of the tongue 5.

Operation: The purpose of the opening formed by the adjacent recesses 16and 17 is to enable the device to be fastened upon the leg of theanimal, this is accomplished by pressing the handles 3 and 4 together,they obtain a bearing upon the tongue 5, which draws apart the abuttingend of the jaw 2 and tongue 5 above their recesses and admits the leg ofthe animal; this movement of the said handles, after the pin 15 has beenwithdrawn from the bolt, also disengages the meeting ends of the tongue5 and jaw 1 for insertion in their recessed portions 11 and 10,respectively, of the tail of the animal. When pressure is removed fromthe handles the forward ends of the device will be brought togetheragain by the spring 8 when the pin 15 may again be inserted in the boltand the device will occupy the position illustrated in Fig. 1. It isreadily seen that the tail may be withdrawn without withdrawing the legof the animal if desired.

What is claimed is In a device of the class described, a pair of jawseach provided with a recess near its forward extremity and terminatingin handles, a pin having its extremities embedded in the said jaws, anapertured tongue mounted on the said pin between the jaws In testimonythat I claim the foregoing 10 provided with recesses in alinement withas my own I have hereto aifixed my signathe recesses of the jaws andterminating at ture in thepresence of two subscribing witone extremityin a point, a spring passing nesses.
